Title:
BRAKE CONTROL DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/134734
Kind Code:
A1
Abstract:
A variable load calculation unit (11) calculates a variable load command VL on the basis of the AS pressure and a predefined table. A vehicle deceleration calculation unit (12) calculates the vehicle deceleration α on the basis of a brake notch command BN and a predefined table. A required brake force calculation unit (13) calculates the required brake force BL by multiplying the load indicated by the variable load command VL and the vehicle deceleration α. An electric brake control unit (14) calculates an electric brake pattern in accordance with the required brake force BL, and sends the electric brake pattern to an inverter control unit. The electric brake control unit (14) calculates the electric brake force generated by operation of an electric motor, and sends the electric brake force, adjusted in accordance with the speed of the electric motor, to a subtractor (15) as feedback BT. The subtractor (15) sends the result of subtracting the feedback BT from the required brake force BL to the mechanical brake as a mechanical brake command.
